Answer:

Here's what I get  

Explanation:

Iron is found in hematite, an ore with the formula Fe₂O₃.

It goes into a blast furnace, where burning coke and a forced supply of air react to form mostly carbon monoxide.

C + O₂  ⟶ CO₂

C + CO₂ ⟶ 2CO

At the high temperatures inside the furnace, the carbon monoxide reduces the hematite to liquid iron.

Fe₂O₃ + 3CO ⟶ 2Fe + 3CO₂

The iron flows to the bottom of the furnace, where it is drawn off.

What mass of fes is formed if 9.42 g of fe reacts with 68.0 g of s8? 8fe(s) + s8(s) → 8fes(s)?
allochka39001 [22]
From the equation, we see that the molar ratio of Fe : S required is:

8 : 1

The moles of Fe present are: 9.42/56 = 0.168
Moles of S = 68/(32 * 8) = 0.265

The molar ratio is:

1 : 1.6

Therefore, iron is the limiting reactant as it is present in a ratio lower than that required. The ratio of

Fe : FeS  is
1 : 1

So 0.168 moles of FeS will form. The mass of FeS will be:

Mass = 0.168 * (56 + 32)
Mass = 14.78 grams

14.78 grams of FeS will be formed.

What is the concentration of hydronium ion in a 0.121 M HCl solution?
kogti [31]

Answer:

C) 0.121 M

Explanation:

HCl + H₂O = H₃O⁺ + OH⁻

.121M              .121M

HCl is a strong acid . It will dissociate almost 100 % so the concentration of acid and hydronium ion formed will be equal . It is to be noted that hydronium ion is formed due to association of H⁺ and H₂O . H⁺ is formed due to ionisation of HCl .

So concentrtion of hydronium ion ( H₃O⁺ ) will be .121 M.
